Where are "this" pointers are assigned ?

[Lacura]

As we all know, in C++, this means a pointer to
the object itself. But where and when is the pointer
created?

I have try the follwing cod:

class A{
A(){ cout<<"A::A() is called."; }
A(int a){ A(); cout<<"A:A(int a) is called"; };
~A(){ cout<<"A is destructing ...";}
}

main(){
A a;
return 0;
}

it shows that in the constructor A::A(int),
another tempory object of A is created.
Then the question is rasied:
Where and when is this be assigned,
at the beginning or at the end of the constructor?

Hi Lacura,

'this' is not created and not assigned.
Every time You instantiate class, first thing is being done -allocating memory block.
Then start address of the memory block is implicitly passed to every non-static
member function (to constructor like to every other n. static member function)

So, 'this' is the keyword, associated with hidden parameter.
